The Scud was clearly out for a photo shoot. The 355 Spider, guarantee that didn't have snows on it (or the driver was a moron, or both.)

Don't put words in my mouth - I said AWD/4WD cars have more traction under acceleration that a comparably equipped RWD car, not that they "perform better."

As for being smart enough, clearly you are ignorant and not in a position to argue the capabilities of an M3 on snow tires without ever having tried it. You stated your opinion early on, if you don't want to drive your car in the winter I really don't give a shit. Don't argue with people when you don't have the facts or experience to do so.
